The transformation of a section of smart street lights on the Guanshen Expressway has been completed, which can save 1.5748 million degrees of electricity annually and increase the brightness of the road surface by more than 10%. In 2008, the scale of my country’s highway intelligent transportation market exceeded 22 billion yuan, and it will continue to grow by 25% in the next five years. In the first quarter of 2011, there were 825 intelligent transportation projects in my country, with a market size of 7.6 billion yuan. There were 621 urban intelligent transportation market projects, with a market size of 2.35 billion yuan, a year-on-year increase of 32.8%.
The Internet of Things looks like a castle in the sky, but it has quietly entered the highway, showing its first appearance.
Drivers who often travel to and from the Dongguan-Shenzhen Expressway will find that the street lights have become brighter when driving on this section of the expressway in recent periods. As early as June of this year, the Dongguan-Shenzhen Expressway, including the second and third phases of the Dongcheng section and the Longlin Expressway, had a total of 2,884 street lights, all of which had undergone energy-saving transformation. The newly replaced street lights on this section of the highway are controlled by a set of Internet of Things control system, which realizes smart management.
With the development of the times, the domestic intelligent transportation market will continue to develop. It is foreseeable that the application of the Internet of Things in expressways will not be limited to street light control systems. In the future, as expressways are upgraded to “smart expressways”, they will be implemented in more places. application.
“ID card” for high-speed street lights
The total length of the Guanshen Expressway is about 56 kilometers. It has been 13 years since its initial completion. The original street lamps have been used for a long time, the equipment is outdated, the lamps are seriously decayed, and the energy utilization efficiency is low. The waste of electric energy is serious, and high daily maintenance costs are required.
The biggest highlight of the renovation project is the introduction of the Internet of Things technology. Through the Internet of Things technology, the smart chip is installed in the street lamp electronic ballast, and each street lamp is named and identified, just like a person has an “identity card”. Then use the existing wires of the street lights for data communication, connect them into a controllable street lamp network, and then connect to the street lamp management center through GPRS and 3G networks, and realize smart energy-saving management of any street lamp through the street lamp management software, and achieve ” “Conversations between people and lights, and between lights and lights” to save a lot of power resources.
Highways can be more intelligent
The Internet of Things system can control street lights, and if cameras or other facilities are installed, more functions can be achieved. With the development of China’s economy, there will be more and more vehicles running on highways, but at the same time, it is urgent to solve the contradictions between cars and roads, traffic and the environment, and the application of the Internet of Things on highways will be more extensive .
In fact, the application of Internet of Things technology in highways has some mature technologies in Europe and the United States. Mainly in the following areas: traffic monitoring and coordination, electronic toll collection and parking management, assisted driving, freight tracking.
If you can make the automatic signal lights smarter. In some highways in Europe and America, automatic signal lights can detect the traffic flow in each direction and each lane through various sensors or cameras, so as to adjust the corresponding traffic light interval accordingly. For example, at many crossroads in the United States, when the traffic is sparse in the middle of the night, the left turn light is generally in the red light state for a long time. Once a vehicle wants to turn left, the system can automatically make the left turn light green. It facilitates the smooth passage of straight-driving vehicles, and also ensures the rapid passage of left-turning vehicles.
Using intelligent transportation technology, it is also very convenient to effectively manage logistics and transportation. Through intelligent transportation technology, transportation companies can track the whereabouts of dangerous goods at any time. In addition, when drivers are speeding and other abnormal driving conditions, they can also issue alarms to ensure transportation safety to the greatest extent. The ability to determine the location of the occurrence in the first time provides great convenience for the follow-up rescue work.
Intelligent transportation enters a period of rapid growth
In 2008, the scale of China’s highway intelligent transportation market exceeded 22 billion yuan, and it will continue to grow at a rapid rate of 25% in the next five years. In the first quarter of 2011, there were 825 intelligent transportation projects in my country, with a market size of 7.6 billion yuan. Among them, the number of urban intelligent transportation market projects is 621, with a market size of 2.35 billion yuan, a year-on-year increase of 32.8%, which is twice the average growth rate in 2010.
In terms of regional development, the construction of intelligent transportation in economically developed cities such as Beijing, Shanghai, and Guangzhou has begun to take shape, while the central and western regions are mainly concentrated in expressway toll systems. The intelligent transportation system within the city needs to be continued to be constructed and improved.
With the acceleration of China’s urbanization process, intelligent transportation as an important part of the Internet of Things industry, the prospects will be very promising. However, there are also some challenges at the moment.
At present, the intelligent transportation demonstration sites are distributed in dots, the scale effect has not been reflected, and the demonstration effect is not obvious. Intelligent transportation products and services are only partially formed, and the satisfaction of travel users is low.
To promote the rapid development of intelligent transportation, government support and guidance are indispensable, and the most important thing for enterprises at present is to put people first, be guided by the application of the Internet of things, and rely on the market to promote development.
